What size ceiling fan do I need to purchase for my room? What size of ceiling fan do I need in my bedroom, living room or kitchen?

This is a common question that often gets asked. The reason this gets asked is, many site visitors want to know what fan they should purchase for the size of room they have. While it may be great to buy a huge fan like a 70″ Harbor Breeze Hydra Ceiling Fan, the question becomes – do I really need a fan this big? The answer is – well, maybe. To figure out the size of fan you need for your room, you can take a look at the below chart.

Which ceiling fan or what size do I need for my bedroom?

The average bedroom size is about 132 square feet while there are bedrooms much larger than even 144 square feet. Based on this information, say you have a bedroom which is under 100 square feet. If this is the case, look at a ceiling fan which is 42 to 44 inches in blade span. If you have a bedroom which is over 100 square feet as mentioned, look at a 52″ to 54″ ceiling fan. As the square footage increases, you can increase the blade span in order to move more air.
